Effect of Inspiratory Muscle Training on Symptom Severity and Quality of Life in Non-Erosive Reflux Disease
Effect of Inspiratory Muscle Training on Clinical Symptom Severity and Quality of Life in Patients With Non-erosive Reflux Disease: A Randomized Controlled Trial
The goal of this clinical trial is to learn if inspiratory muscle training (IMT) works to treat on clinical symptom severity and quality of life in patients with Non-erosive reflux disease (NERD). The main questions it aims to answer are:
Does drug IMT lower the clinical symptom severity ? Does drug IMT improve quality of life? Researchers will compare high intensity IMT to a sham-IMT (a IMT device with no resistance) to see if IMT lower the clinical symptom severity and improve improve quality of life.
Participants will perform the following protocol:
The IMT protocol will consist of home-based high-intensity training using a Threshold IMT device: two sets of 30 breaths with a 1-minute rest, twice daily for 4 weeks. The study group will train at 60% of baseline maximum inspiratory pressure (MIP), with weekly adjustments based on modified Borg scores (4-6), while the control group will perform sham IMT without resistance.

Deltakergruppe / Arm |
Intervensjon / Behandling |
|---|---|
|
Eksperimentell: Study Group
Patients who will perform inspiratory muscle training (IMT) with %60 loading
|
The IMT protocol will consist of home-based high-intensity daily training - two cycles of 30 breaths with a 1-min rest between sets, twice a day for 8 weeks using an IMT Threshold device (Threshold IMT Philips® Respironics, Inc).
The intensity of the training will be set to 60% of each patient's maximal inspiratory pressure, measured and adjusted weekly based on the modified Borg scale from 4 to 6 regarding respiratory effort performed during the session.
|
|
Sham-komparator: Sham Group
Patients who will perform Sham IMT
|
IMT-protokollen vil bestå av hjemmebasert daglig trening - to sykluser på 30 pust med 1 min hvile mellom settene, to ganger daglig i 8 uker ved bruk av en IMT-terskelenhet (Threshold IMT Philips® Respironics, Inc.).
Intensiteten på treningen vil bli satt til den laveste intensiteten til IMT Threshold-enheten.

Tiltaksbeskrivelse |
Tidsramme |
|---|---|---|
|
Symptom Severity
Tidsramme: 4 weeks
|
The Reflux Disease Questionnaire (RDQ) will be used to measure the severity of clinical symptoms.
The RDQ is a 12-item self-report scale that assesses the frequency and severity of upper gastrointestinal symptoms over the past week.
Each item is rated on a Likert scale from 0 to 5, and the total score is calculated as the average of the relevant items.
A higher score indicates more severe symptoms.

Inspiratory Muscle Strength
Tidsramme: 4 weeks
|
The Inspiratory muscle strength was evaluated by maximum inspiratory pressure which was assessed with a digital mouth pressure meter device (MicroRPM, Micro Medical Ltd., Rochester, Kent, United Kingdom), and recorded in cmH2O (centimeter-water).

Gastroesophageal Reflux Disease-Related Quality of Life
Tidsramme: 4 weeks
|
The Gastroesophageal Reflux Disease Quality of Life Questionnaire (GERD-QOL) will be used.
The questionnaire will be evaluated based on the total score, with a higher score indicating poorer quality of life.
